Introdução

The main thing that usually breaks on a jump starter is the battery. These units usually contain a lead acid battery with a finite lifespan. It is possible and simple to replace but usually not financially worth doing. If the unit does not hold a charge but functions while it is plugged in then it is most likely a faulty battery.

Opening it up reveals the Lead battery, AC/DC converter, 12V DC input, switch, back of circuit board, back of light.

Additional bells and whistles are sometimes added (lights, switches, compressors, power jacks, etc.) Some have AC power jacks which require a DC/AC converter which is more expensive than an AD/DC converter.

I am 99% sure that you will never find that part. any of these components aren't really meant to be replaced. Things like the battery or the ac-dc converter you can find because they just used off-the-shelf parts. You could probably find that size hose but you would have to find a way to seal/crimp it onto the air nozzle on the other end.

Truth is that all these jump starter/compressor combos are Chinese imported junk. You can extend it’s life if you purchase it new from store and charge that battery 72 hours before ever touching anything else on the unit. Never set or store the unit on bare concrete and if you can avoid it never use the compressor once. If you must then leave it on a maximum of 2 mins a use and full recharge after each use. These units are actually pretty well made and very durable. No fuse will save a defective one of these units because no fuse in it. Never purchase any item needing these type of lead sealed batteries. They’re all defective and just being sold in every possible item they can use them in because theyre dirt cheap and lead. They already have much cheaper and far more reliable versions of these batteries and wont update because they have a cash income source with the defects that just keeps giving and giving. Razor Scooter, best built scooter youll find, rechargeable sealed batteries make them junk.

Its the sealed batteries. Purchase no product that uses these. Defective in Razor Scooters and all forms of medical scooters, all electric toy cars and the electric shopping carts in stores..Already have lithium batteries that can remedy all of the above..why havent they? Why isnt it an option at purchase? The jump starters cant be lithium until the car batteries are. Why arent they both? Called robbing the consumer. Dont purchase any item with lead sealed rechargeable!!!
